Is kinetic energy equal to elastic potential energy?
As the object starts to move, the elastic potential energy is converted into kinetic energy, becoming entirely kinetic energy at the equilibrium position. The energy is then converted back into elastic potential energy by the spring as it is stretched or compressed.
Can you crush someone’s skull with rubber bands?
The average adult male’s skull can withstand up to 2300N before it gives. Given the average circumference is 57cm, it would require just over 150 office standard rubberbands to crush your skull in the temporal region. A rubber band is stretched back so that it stores 1.5 J of energy.
How much rubber bands does it take to explode a watermelon?
Learn more about embedding Facebook videos on our developer site. After more than two hours and about 863 rubber bands, the watermelon finally exploded.
What happens when you put a rubber band around a watermelon?
When we add rubber bands to the watermelon, we are applying a force to the outside of the watermelon. The inelastic deformation coupled with the force from the potential energy from the rubber bands eventually causes the watermelon to burst.
How many rubber bands does it take to explode a pumpkin?

How many rubber bands does it take to make a ball?

Why does a pumpkin explode with rubber bands?
At first, the pumpkin is at rest. But as you add rubber bands to the pumpkin, those rubber bands gradually begin transferring force to the shell of the pumpkin, causing an inelastic deformation on the outside of the pumpkin.

What size rubber band should I buy?
To measure a rubber band:
- Pinch a rubber band at each end to lay the band flat. The distance from end to end is the flat band length.
- The width of the flat band measures how wide the band is, perpendicular to the length.
- The wall measures the thickness of the band.
